dc.description.abstractData on different conformation, production and reproduction traits were collected from 120 indigenous Keonjhar goats after collecting weights and measurements of the body. The data that correspond were also collected from 120 Black Bengal and 120 Ganjam goats for comparison. The mean values of weight at birth in male Keonjhar, Black Bengal and Ganjam goats were 1.36±0.20, 1.41±0.20 and 2.68±0.22 kg, respectively. Correspondingf mean valuessin female goatsswere 1.28±0.22, 1.30±0.21 and 2.55±0.22 kg, respectively. At adult stage, the male Keonjhar, Black Bengal and Ganjam goats achieved 15.85±0.21, 24.40±0.23 and 41.39±0.20 kg of body weight, respectively. The values that correspond in case of female goats were found to be 14.90 ± 0.23, 22.31±0. 88 and 30.31±0.52 kg, respectively. All the body morphometric traits were positively correlated among each other in this study. Females of Keonjhar, Black Bengal and Ganjam goats came to heat at 229.18±1.88, 279.89±2.15 and 440.46±1.79 days, respectively and dropped their first kids at 395.25±1.45, 469.73±2.68 and 618.68±1.84 days, respectively. The average size of litter in female Keonjhar, Black Bengal and Ganjam goats were found as 1.77±0.47, 1.97±0.73 and 1.02±0.14, respectively. All the conformation and reproductive traits varied significantly (p<0.05) among the three goat populations. However, Keonjhar and Black Bengal goats didn’t show any significant difference with regard to tail length and gestation length. Keonjhar goats showed significantly lower estimates for all the conformation traits than other two goat populations with satisfactory reproductive performance. DNA isolation was carried out from the buccal swab samples of Keonjhar goats and the complete coding region of the Nerve Growth Factor (NGF) gene was amplified using the specified primers. Sequence alignment with the reference sequence confirmed the presence of a synonymous mutation (C291A) in this population. The gene frequencies of C and A allele were found to be 0.74 and 0.26. The does with CA genotypes showed higher litter size than CC genotype (p<0.05). The findings indicate that NGF gene can be put to use as a candidate gene for the improvement of the size of the litter in these population of goat. The nucleotide sequence of NGF gene in goat is in close similarity with sheep, cattle, buffalo and wild yak. The value of theoretical isoelectric point (PI), instability index, aliphatic index and GRAVY value for NGF protein were predicted as 9.81, 45.73, 74.90 and -0.287, respectively. The secondary and tertiary structure of NGF protein were predicted as well. Ten putative interacting proteins of goat NGF protein were predicted.en_US
